Overcoming Sunk Cost Fallacy: When to Cut Your Losses

The sunk cost fallacy keeps you committed to failing endeavors. Learning when to cut losses transforms decision-making.

You've invested so much already—you can't quit now. This logic drives terrible decisions. The time and resources spent are gone regardless of your next choice.

The Sunk Cost Fallacy

Sunk costs are past investments that can't be recovered. Rational decisions should consider only future costs and benefits, not past investments. But emotionally, abandoning something we've invested in feels like admitting waste.

Don't let past investments drive future decisions.

Breaking Free

• Ask forward-only: What are the future costs and benefits?
• Separate identity: Quitting isn't failure
• Quantify: What's the additional cost to continue?
• Embrace endings: Closing doors opens new ones

Let go of what's gone. Focus only on what comes next.
